HEMMING ATTACHMENT FOR SEWING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 414,914, dated November12, 1889.

Serial No. 282,733. (No model.)

To all whom it may concern:

Be it known that I, ALICE LA GUAYRA MAYO, of Great Falls, in the countyof Gascade and Territory of Montana, have invented a new and ImprovedPresser-Foot Hemmer, of which the following is a full, clear, and exactdescription.

My invention relates toan improvement in hemmers, andis especiallydesigned for hemming all articles that require a wider hem than theordinary fell; and the object of the invention is to provide a devicewhich will turn a hem from, for instance, a quarter of. an inch to aboutseven and a half or eight inches in width, and also to provide a meanswhereby a draw-string, ribbon or tape may be inserted in the hem; andthe further object of the invention is to provide a hemmer which willhave a double gage and be constructed in a simple, durable, andthoroughly practical manner.

The invention consists in the construction and combination of theseveral parts, as will be hereinafter fully set forth, and pointed outin the claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1 is a perspective view of the hemmer, and Fig. 2 is a sideelevation of the same. Fig. 3 is a view showing the attachment inposition during the operation of turning a hem and inserting a ribbon ortape.

In carrying out the invention, A represents abody-bar provided with avertically-apertured post A, integral with the upper face near one endand at one side, into which post the presser-bar of the machine issecured through the medium of a set-screw a, passing through said postto a contact with the needlebar. The said post A is provided upon oneside with a recess a intersecting the bore or aperture adapted for thereception of the needle-bar, which recess a is purposed to accommodatethe presser-foot.

The frame ofthe hemmer consists of two side bars B and B, the side bar Bbeing the wider of the two and provided with a longi tudinal slot 12 anda scale of inches b, produced upon the upper face, preferably at theouter edge. The side bar B is made to rest in a suitable recess formedtransversely in the upper face of the body-bar A at or near the end ofsaid bar, as best illustrated in Fig. 1, the said side bar B being ad justably held in connection with the body-bar through the medium of aset-screw b passing through the slot b of the side bar into thebody-bar; but if it is found desirable in practice the set-screw b maybe substituted by a rivet, the rivet being so located as to permit theside bar B to readily yet not too freely slide upon the body-bar. Theopposing side bar B is passed through a transverse slot produced in thebody-bar at or near the end, to which the slotted side bar B is secured,and the two side bars B and B are pivotally connected at their outerends by a cross-bar O, which cross-bar rests upon the upper surface ofthe said side bars, as illustrated in the drawings. A forward cross orguide bar D is formed integral with the slotted side bar B, extending atright angles therefrom a distance beyond the smaller side bar B. Thesaid inner guide or cross bar D is bent downward upon itself at rightangles to form a vertical flange (1, whereby the said guide-barpal-takes of the contour of an angle-iron. A second and under guide-bar.E, which more properly may be designated a retainingbar, is formedintegral with the narrow side bar B, extending at right angles theretoin direction of the slotted side bar B and beneath and in engagementwith the horizontal member of the guide-bar D, as best illustrated inFig. 1. The retaining-bar E is also continued beyond the outer edge ofthe side bar B to support the extension of the guidebar D. Between thepost A and the side bar B the hemmer proper H is secured to the edge ofthe body-bar contiguous to the guidebar D, which hemmer maybe of anydesired construction, but is formed of one or two pieces of metal,preferably the latter, bent so as to represent in cross-section theletter U, and having one under edge turned upward and inward to curlover the fabric as it passes through to receive the stitch.

In operation the body-bar is slid upon the side bar until the inner faceof the said bodybar is made to register with the inch or fraction of theinch to which the hem is to be turned.

The material is then passed under the entire frame and body-bar, carrieddown in direction of the guide-bar, and passed over the retaining-barand beneath the guide-bar and into the hemmer. A ribbon or tape may beinserted in the hem by placing the same beneath the gage. In lace it canbe used as a border, and in heavy material as a drawstring. Space mustbe left to remove the gages, and in very wide hems the hemmer should beremoved from the machine.

Having thus described my invent-ion, what I claim as new, and desire tosecure by Letters Patent, is-

1. The combination, with the body-bar A, provided with an apertured postadapted to receive the presser-bar, and a hem-former II, secured to thesaid body-bar, of an adjustable frame consisting of a slotted side barB, having a scale produced thereon, adjustably secured to the body-bar,a transverse-angled guide-bar D, secured to the slotted side bar, anopposing narrower side bar B, sliding in the body-bar, a transverseretaining-bar scoured to the said narrow side bar, engaging the underface of the guide-bar, and a crossbar 0, pivotally securing one end ofthe said side bars, all combined to operate substantially as and for thepurpose specified.

2. As a new article of manufacture, a hemmer attachment forsewing-machines, consist-i ing of the body-bar A, provided with anapertured post adapted to receive the presserbar of the sewing-machine,and a hem-former secured thereto, an adjustable frame consisting ofslotted side bar 13, having a guide-bar D at one end, an opposing sidebar B, provided with a retaining-bar engaging the guidebar, and apivoted cross-bar C, all adapted to operate substantially as and for thepurpose described.
